IGN has exclusively unveiled a trailer for the LEGO Batman: Legacy of the Dark Knight Deluxe Edition - Mayhem Collection DLC, showcasing the upcoming Harley Quinn and The Joker story mission, Mayhem Mode, and Sinister Pack. This DLC will be free for Deluxe Edition owners on September 18, 2026, coinciding with the game's launch on Nintendo Switch 2.
The new Harley Quinn mission tasks her with breaking out of Arkham Asylum, accompanied by her hammer, Fun Gun, and hyenas Bud & Lou. The Joker will bring a paintball launcher and boxing glove to the fray, sporting a fast-paced combat style. Both characters will unlock special outfits inspired by past Batman media. In the Mayhem Mode, players will lead Harley Quinn and The Joker on time-limited missions across Gotham City, avoiding Batman and Robin while battling A.R.G.U.S. agents and other villains.
The Sinister Pack will introduce themed outfits, a new vehicle, and Batcave customization options. Additionally, an enhanced Absolute difficulty level will be released as a free update, demanding greater skill and precision in combat. LEGO Batman: Legacy of the Dark Knight was initially released on PS5, Xbox Series X/S, and PC in May 2026, receiving praise for its open-world Gotham and Lego-inspired humor.
